Main objectives

Development and production of electro-optical devices for image registration and measurement of high-speed processes, such as:

combustion, explosion, shock and detonation waves, dispersion of soil or elements of shells and structures, ballistics of bodies cast up to cosmic velocities, and their interaction with the obstacle or target

natural (lightning) and artificial electrical discharges in gaseous and other environments

various pulsed radiations in the range of near infrared to hard X-ray radiation, including laser interaction with substances of different types of radiation: weak (with biological objects), powerful and super powerful such as optical, including laser one and corpuscular (electronic, ionic and other beams), etc.

Laboratory produces electrooptical transducers (EOT) and high-speed cameras on their basis, as well as auxiliary equipment, such as pulse illuminators, photosensors to synchronize cameras and others. Limiting temporal resolution of the cameras is in the femtosecond range

Laboratory specialists deliver cameras to the users, as most of produced cameras are the smallest in the world, put them into operation at the customer site, train the users, conduct presentations of equipment, joint demonstration experiments and research

Laboratory provides one or two year warranty for the equipment, and maintenance of its efficiency for up to 10 years
